Devices plugged into people’s skulls are being developed by boffins funded by the US military’s research division DARPA.
These implants will use electronic pulses to alter the chemicals in people’s brains in a process called “deep brain stimulation”.
This will then change people’s moods and is believed to be able to treat mental illness and provide therapy.
Artificial intelligence in implants will detect and study the brain to know what pulses to send – described by scientists as a “window on the brain”.
DARPA has handed the cash to teams form the University of California and Massachusetts General Hospital.
